The Romans used the word "fasces" to decribe a bundle of sticks bound together to hold an axe at one end (a picture would be worth a lot but I don't have one). The cord was wrapped around the bundle. The axe was used in war as well as construction. Benito Mussolini and the Italians knew about this, being well steeped in Italian, i.e., Roman history. Beniti coined fascist from "fasces" telling the Italians that they were strong if bound together. History lesson for the day.

The prime factors of 2^29 - 1 are 233, 1103, and 2089. The equation 2^29 - 1 = 233 * 1103 * 2089 gives the _factorization_ or _complete factorization_ of 2^29 - 1. Whereas 2^29 - 1 = 233 * 2304167 (where 2304167 = 1103 * 2089) 2^29 - 1 = 1103 * 486737 (where 486737 = 233 * 2089) 2^29 - 1 = 2089 * 256999 (where 256999 = 233 * 1103) are _partial factorizations_ of 2^29 - 1. A complete factorization factors a number into prime factors. A partial factorization allows composite cofactors (which are smaller than the original number). If someone finds the factor 233 of 2^29 - 1, he/she can compute the cofactor 2304167, and subject the cofactor to a probable prime test. If the cofactor is definitely composite, we have only a partial factorization, and more work is needed. If instead the cofactor passes the probable prime test, we try to prove it prime so we can be sure the factorization is complete. ________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm ------------------------------ From: Henk Stokhorst <[EMAIL PROTECTED]> Date: Thu, 18 Feb 1999 08:48:11 +0100 Subject: Re: Mersenne: Completely Factored Sander Hoogendoorn wrote: > Can sombody please tell me when a number is completely factored?

I have been having trouble keeping it running; it seems like the System Idle Process will take control of the CPU. Things will run fine for a day or two; NTPrime will start automatically and when I check the Task Manager it is using 99% of the CPU. But then I will come back a day or so later and sometime during that time period the System Idle Process took control and is running at 99% CPU usage and NTPrime has 0%. To get things corrected, I have tried increasing the priority of NTPrime. This did not help. I also tried rebooting the machine. This did not help. What did work was to stop the Prime Service, remove the service, reboot the machine, reinstall the service, and then start the service again. Before I starting running NTPrime, I ran Prime95 under Windows NT on this Dell computer. However, I ran it manually instead of automatically like I am now. Is there an explanation why the System Idle Process is taking control of the CPU? Thanks in advance for any help.
